Once doubt set in, scientists began to accumulate statistics about the practice, finding that a large minority and then a large majority of people masturbated. The implications were clear: if most people masturbated and did not experience insanity, debility, and early death, then masturbation could not be held accountable to the etiology that had been assigned it. Masturbation quickly lost its hold over the medical community, and parents followed in making masturbation an ordinary part of first childhood and then human sexuality.”.

Subsequent research, outlined by Coleman in this chapter, has shown masturbation to be linked to healthy sexual development, sexual well-being in relationships, self-esteem and bodily integrity (an important sexual right). As such, the promotion and de-stigmatization of the practice continue to be important strategies within sexology for the achievement of healthy sexual development and well-being.

The collection concludes with two surveys among US college students. The first of these was based on limited quantitative questions relating to masturbation. The findings suggest that masturbation is not a substitute for sexual intercourse, as has often been posited, but is associated with increased sexual interest and greater number of partners. The second of these surveys asks whether masturbation could be useful in treating low sexual desire, by examining the relationship between masturbation, libido and sexual fantasy.”.

^Confirmat de The Web Bible Encyclopedia pe enhttp://www.christiananswers.net/dictionary/onan.html citat: „Some have mistakenly assumed that Onan's sin was masturbation. However, it seems clear that this is not the case. Onan was prematurely withdrawing from sexual intercourse with his new wife, Tamar. This is a form of birth control still practiced today (coitus interruptus).”

Citat: „The Bible mentions at least one form of contraception specifically and condemns it. Coitus interruptus, was used by Onan to avoid fulfilling his duty according to the ancient Jewish law of fathering children for one’s dead brother.”
